IMPORTANT MESSAGE

YOU are responsible for the SAFE operation and maintenance of your Valmetal SILO UNLOADER

MODEL 880-SK. YOU must ensure that you and anyone else who is going to install, operate,

maintain or work around the SILO UNLOADER be familiar with the installation, operation and

maintenance procedures and related SAFETY information contained in this manual. This manual will

alert you to all good safety practices that should be adhered to while operating the SILO UNLOADER.

Remember, YOU are the key to safety. Good safety practices not only protect you but also the people

around you. Make these practices a working part of your safety program. Be certain that

EVERYONE operating this equipment is familiar with the recommended operation and maintenance

procedures and follows all the safety precautions. Most accidents can be prevented. Do not risk injury

or death by ignoring good safety practices.

SILO UNLOADER owners must give operation instructions to operators or employees before allowing

them to operate the machine, and at least annually thereafter per OSHA 1928.57.

The most important safety device on this equipment is a SAFE operator. It is the operator’s

responsibility to read and understand ALL Safety and Operating instructions in the manual and to

follow these. All accidents can be avoided.

A person who has not read and understood all installation, operating and safety instructions is not

qualified to operate the machine. An untrained operator exposes himself and bystanders to possible

serious injury or death.

Do not modify the equipment in any way. Unauthorized modification may impair the function and/or

safety and could affect the life of the equipment.

Think SAFETY! Work SAFELY!


WARNINGS ON SILO UNLOADER


This sign must be installed at the silo base near the ladder (chute)… TO BE SEEN BY ALL.


Silage fermentation may produce several kinds of

gas, including carbon dioxide and nitric oxide

(which then produces nitrogen dioxide). Carbon

dioxide is non-poisonous, although it can cause

suffocation.

Nitrogen dioxide (NO2), however is poisonous. It

kills and injures people as well as livestock.

Nitrogen dioxide is a hazard on the farm because:

1. Exposure can be fatal.

2. Formation of nitrogen dioxide from nitric oxide

may occur whenever silage is made.

WHAT IS THIS GAS ?

The lethal gas is yellowish-brown and smells like

some laundry bleaches. After more oxidation, it

forms N2O5 which then forms highly-corrosive nitric

acid when combined with water. Since oxidation

may occur in the body, nitrogen dioxide can produce

permanent lung damage.

WHERE DOES IT HIDE?

Since nitrogen dioxide is heavier than air, it remains

beneath the air mass over the silage. It layers on top

of the silage below the upper edge of the top door or

settles down through the chute. It may also seep

through the drain at the base of the silo. If often

concentrates in the silo room and move into the

barn. It will leave a yellow stain on silage, wood or

other materials it contacts.

HOW TO MINIMIZE THE DANGER

While growing the crop :

1. Apply adequate nitrogen, but don’t over do. As

a guide, corn needs 1.2 lbs. of N per bushel

yield; oats and/or sudangrasse used for silage

should have no more than 75 lbs. of N available

for each harvest. Since this includes both N in

the soil and that applied, follow the

recommendations on soil analysis reports.

2. After a drought, rapid nitrate uptake occurs in

plants following rain. So, harvest the crop

before fall rains, or wait at least five days after a

rain.

3. Plants damaged by hail or frost should be

harvested immediately before they take up

nitrates.

4. To reduce the amount of nitrate going into

silage, cut higher than normally (10-12 inches).

Most nitrates are in the lower stalk.

While filling the silo :

1. Be on the alert for bleach-like odors and/or

yellowish-brown fumes in or near the silo.

Small amounts of the gas may not be visible or

easily detected by smell, but are still dangerous.

(Greatest danger is 12 to 60 hours after filling

silo).

2. If you must enter the silo, run the silage blower

for 15 or 20 minutes first. Never enter the silo

alone during the danger period and always have

someone outside of the silo to communicate

with.

3. If you experience the slightest throat irritation or

coughing while in the silo, get into fresh air

immediately. Call your doctor as soon as

possible, indicating that you have been exposed

to silo gas.

DANGER

NEVER ATTEMPT TO RESCUE A PERSON

WHO HAS BEEN OVERCOME BY SILO GAS

WITHOUT THE AID OF OXYGEN-

SUPPLYING BREATHING EQUIPMENT.

FAILURE TO HEED MYA RESULT IN

SERIOUS PERSON INJURY OR DEATH.

After filling the silo :

1. Ventilate silo room to outdoor air for at least

two weeks.

2. Keep any door between silo room and barn

closed to minimize any risk to livestock.

3. Remove upper silo chute doors down to the

settled silage level to prevent build-up of gases

in silo.

DANGER: SILO GAS IS HAZARDOUS


2.1 GENERAL SAFETY

1. Read and understand the Operator’s Manual and all

safety signs before operating, maintaining or

adjusting the SILO UNLOADER.

2. Have a first-aid kit available for use should the need

arise and know how to use it.

3. Have a fire extinguisher available for use should the

need arise and know how to use it.

4. Wear appropriate protective gear. This list includes

but is not limited to :

- A hard hat

- Protective shoes with slip resistant soles

- Protective glasses or goggles

- Heavy gloves

- Hearing protection

5. Install and secure all guards before starting.

6. Wear appropriate ear protection for prolonged

exposure to excessive noise.

7. Clear the area of people before starting the unit.

8. Review safety related items annually with all

personnel who will be operating or maintaining the

SILO UNLOADER.

9. Always call upon a qualified electrician for electrical

problems.

10. Do not get near the Unloader auger when it is in

operation. The auger is equipped with very

sharp knives. These knives can seriously injure

anyone who gets close to the auger. Keep hands

and feet away from auger. Also, make sure no

on is near the auger when it is operating.

2.2 OPERATING SAFETY

1. Read and understand the Operator’s Manual and

all safety signs before operating, servicing,

adjusting, repairing or unplugging.

2. Be certain that all guards and shields are secured

before starting or operating.

3. Make certain everyone is clear of equipment

before applying power.

4. Always lock out power source before entering a

silo.

5. Keep hands, feet, hair and clothing away from

moving parts.

6. Be sure main switch is off before resetting

motor thermals.

7. Never stand underneath a suspended silo

unloader.

8. Never work or crawl on a silo unloader that is

suspended. Always lower silo unloader to silage

level to work on it.

9. Always leave at least three feet of suspension

cable between the suspension arms and the cable

pulleys. Snubbing the unloader any tighter at

the top could cause undue strain on the

suspension, which might cause the unloader to

fall.

10. Never go into a silo to work on a moving silo

unloader, stay in silo chute to observe operation.

11. Never disconnect the electrical cord connector if

the silo unloader is running because moisture

conditions inside the silo could give you a

severe shock.

12. Always inspect suspension cables carefully

before you raise unloader to top of silo.

13. Beware of silo gases, read carefully page 6.

THINK SAFETY and live longer.

A careful operator is the best insurance against an accident.

The complete observance of one simple rule would prevent many thousands of serious injuries each year.

That rule is ¨NEVER ATTEMPT TO CLEAN, OIL, OR ADJUST A MACHINE WHILE IT IS IN MOTION¨.

Regardless of care used in the design and construction of farm equipment, there are many points that cannont be

completely safeguarded without interfering with accessibility and efficient operation.


2.3 MAINTENANCE SAFETY

1. Follow ALL the operating, maintenance and

safety information in the manual.

2. never go into a silo to work on a moving silo

unloader. Stay in silo chute to observe

operation.

3. Always shut off and lock up main power switch

before entering silo.

4. Never walk or crawl on the unloader when it is

suspended above the silage surface or when it is

operating.

5. Be sure electrical outlets and tools are properly

grounded.

6. Use adequate light for the job at hand.

7. Keep hands, feet, hair and clothing away from

moving parts.

8. Never wear ill-fitting, baggy or frayed clothing

when working around or on any of the drive

system components.

9. Clear the area of bystanders, especially small

children, when carrying out any maintenance

and repairs or making any adjustments.

10. Never use a suspended unloader as a substitute

for a scaffold.

2.4 SAFETY DECALS

1. Keep safety decals and signs clean and legible at

all times.

2. Replace safety decals and signs that are missing

or have become illegible.

3. Replaced parts that displayed a safety sign

should also display the current sign.

4. Safety decals or signs are available from you

Dealer Parts Department or the factory.

How to install Safety Decals :

Be sure that the installation area is clean and

dry.

Decide on the exact position before you remove

the backing paper.

Remove the smallest portion of the split backing

paper.

Align the decal over the specified area and

carefully press the small portion with the

exposed adhesive in place.

Slowly peel back the remaining paper and

carefully smooth the remaining portion of the

decal in place.

Install auger knives to auger with 1/4" x 5/8" hex. bolts and nylon lock nuts

SECURE ANCHOR CHAIN

Note : Disregard if the unloader is equipped with a torque

arm.

Assemble the anchor chain over the suspension cable at the

right side of the silo door (looking from the silo chute).

Attach the chain to a silo hoop or the door sill. Allow

about one foot of sag at the center of the chain.

TEST RUN

Raise the unloader above the silage to do a test run and check the following :

1- Make sure the skates slide freely and the ring segments are flush. If not, bend ring flange so there is no

interference.

2- Be sure chipper blades are held close to, but not in contact with the silo wall all the way around.

3- Be sure the belts are running true and the sheaves are in line.

ADJUSTING THE SILO UNLOADER

PRESSURE WHEEL, GUIDE WHEEL AND WALL WHEELS.

1-The pressure wheel should run against the silo wall at all times. Its purpose is to hold the auger wall wheels in contact with the silo

wall and to insure that all material is removed from the wall area. Normal adjustment of the pressure wheel is when the spring is extended

4". During extremely frozen conditions, it may be necessary to increase the spring force. This is done by moving the hook on the spring to

a different chain link when tension is released. After changing pressure wheel adjustment, you should always watch the unloader rotate

around the silo at least once to make sure that your adjustment will not cause the pressure wheel to exert force on the unloader. Observe

operation from safety of silo chute.

2-The unloader is kept centered in the silo by the side guide wheel , this is the one extending out at approximately a 90 degree angle

from the auger. The guide wheel should run against the silo whall at all times. You can get the correct setting for this wheel by first

measuring the maximum silo diameter. Then extend the wheel so that the distance from near side of the impeller housing to the edge of

the wheel is equal to one half the maximum diameter of the silo. You can tell when this adjustment is incorrect by a pile of undisturbed

silage being left in the center of the silo directly under the impeller housing. If this occurs, the wheel is probably not extended out far

enough.

3-The position of the wall wheels in relation to the auger, determines the closeness of the chipper knives to the silo wall. This is very

critical in freezing weather and should be set so the chipper knives are within 1/8" of the silo wall. Adjust by loosening the bolts wich

secure the wall wheel bracket to the auger frame and turn the adjusting screw out or in to obtain the correct adjustment. After you make

any change in the wall wheel setting, rotate the unloader around the silo to make sure the chipper blades do not hit the wall at any place.

Observe operation from safety of silo chute. The trailing wheel will generally be in contact with the silo wall except near the silo doors.

As the machine approaches a door, the lead wheel will come in contact with the flattened wall and protect it from being damaged by the

chipper knives.


OPERATING THE SILO UNLOADER

For trouble-free operation of your silo unloader, the following operator schedule is recommended.

After turning off the silo unloader at the end of feeding, raise the machine off the silage pack.

During extreme cold weather if the motor switch is turned on and off momentarily after raising, this will clear the impeller

of any material left in it for easier starting at the next feeding. To begin feeding again, lower the unloader the same

amount that it was raised previously. Now turn on the motor switch.

When you turn on the silo unloader, the needle will flick over to a maximum reading. The ammeter is designed so that this

initial surge of current will not damage it. A couple of seconds after starting, the ammeter will level off at the normal load

current for your motor. Most reliable, efficient operation and highest capacity will be obtained when you operate your silo

unloader motor in its proper amperage range.

After the unloader has completed its revolution around the dilo, the silage flow will decrease and the unloader should

again be lowered the amount necessary to load the motor to rated current. Observation will tell you how many turns of the

crank are necessary to do this. Five turns lower the unloader about one inch. Slight overloading or underloading will not

damage the equipment and is much better for it than continuous jockeying up and down the hoist.

A complete revolution around the silo will take about 5 minutes. Should any obstruction occur in the silo during this 5

minutes period, a built in clutch will prevent damage to the equipment.

If the impeller should become plugged due to long hard-to-handle material or rotten material from the top of the silo, the

stall current of the motor is such that it will trip the overload device in the control box at the bottom of the silo before

damage is done to the motor or the unloader. Whenever this happens, you should go up and find the cause of the

stoppage before attempting to restart the unloader.

The curved discharge chute is designed to allow maximum lowering for a given size of silo before it is necessary to move

the discharge chute down to another silo door. This discharge chute should be lowered every two doors. This would

be a good opportunity for you to take the time to check your unloader.

DISCONNECT AND LOCK OUT POWER SOURCE BEFORE ADJUSTING

OR SERVICING UNIT.

1- Before entering the silo chute be sure the power to the unloader has been turned off and locked.

2- If your unloader is equiped with a remote control switch, lock the stop button down so the unloader cannot be

started accidentally and take the remote switch with you.

3- As soon as you climb the silo chute to the door through which the material was being thrown out, reach into the

silo and unplug the power cord to the silo unloader.

4- Remove the torque arm bracket from the door frame and lower it.

5- Unless equiped with cord looping, unhook the power cord grip and reattach it to a ladder rung just above

the next discharge door you will use.

6- Before leaving the silo you should check the machine over thoroughly.

7- After you are out in the silo chute, plug the cord connectors together before climbing down.


LUBRICATION TO BE MADE BEFORE

STARTING-UP UNLOADER AND MONTHLY

COLLECTOR RING

Grease both grease fittings on the upper support bearing of the collector ring with two pumps from a hand

grease gun. Avoid over greasing as it is possible to damage the collector ring seal and get grease down

into the electrical contact area.

Lubricant level should be check in the ring drive gearbox every time you go into the silo to change

door; this is accomplished by viewing the oil level through the sight plug located on the gearbox. If

lubricant level is low, add EP 80-90 high pressure gear lubricant.

The gear lubricant level in the auger gearbox should also be checked every time you go into the silo to

change door. If lubricant level is low, add synthetic oil Shell Spirax S75W90.

OIL LEVEL

OIL FILLER PLUG

The lubrication level in the worm gear hoist should be checked every 6 months and every time you will raise the

unloader to the top of silo. The oil level should be visible in the oil level sight plug. If oil is low, add

EP 80-90 extreme pressure gear lubricant. Lubricant should be changed annually.

The hoist cable assembly will have a much longer life if lubricated with motor oil or gear lubricant.

You should do this when the unloader has been raised to the top of the silo and all the cable is wrapped on the

hoist.Paint on a liberal coat and allow it to drip off.


IMPELLER BLADES AND V-BELTS

IMPELLER BLADES

The impeller on this silo unloader can be operated with the blades rigid, as sent from the factory, or as swinging

blades by removal of 3 locking bolts. If the blades are left rigid, the maximum throwing power will be achieved. It

is recommended to remove the 3 locking bolts to allow the blades to swing if material being unloaded causes

extreme gumming or during extreme cold weather operation. If the blades are allowed to swing, silage will fall out

from the discharge chute when the machine is started or stopped and anytime the unloader is overloaded causing

drop in motor speed.

The blades are also adjustable by loosening the 3 grade 5 carriage bolts securing the cupped blade to the blade

bracket. The clearance between the blade tip and rim sheet should always be within 1/32". Proper tightening torque

on these bolts is 40 lbs-ft.

V-BELTS

During initial unloading operation, some stretch of the impeller and auger belts may occur, and belts should be

readjusted. To tighten these drive belts, loosen the 4 horizontal carriage bolts through the motor mount, move

motor mount away from impeller with take-up "J" bolt and tilt motor plate upward with 1/2" hex. bolts on under

side of motor mount. If auger belt becomes tight before impeller belt, then motor plate must be lowered while

moving motor mount further away from impeller. If impeller belt becomes tight before auger belt, then motor

mount must be moved back toward impeller while raising motor plate with set screws. Adjustment in the

horizontal direction and upward direction must be made together so that both belts become tight at the same time.

The correct tension for the impeller belt may be determined by placing a 6 pounds force at the mid-point between

the 2 pulleys. This should depress the belt 1/4" to 3/8". The correct tension for the auger drive belt may be

determined by placing a 6 pounds force at the mid-point between the 2 pulleys. This should depress the belt 1/8" to

3/16".

Avoid overtightening belts. It may cause bearing damage.

After the belts are properly tensioned, tighten the 1/2" lock nuts on the 1/2" adjusting bolts, lock the 3/8" nut on

take-up "J" bolt, and tighten four horizontal carriage bolts.


CONVERTING FROM UNLOADING TO DISTRIBUTING

DANGER

DISCONNECT AND LOCK OUT POWER SOURCE BEFORE

CONVERTING TO UNLOADING.

IMPORTANT :

Impeller must not be turning when using distributor.

On the line shaft drive model, the impeller V-belt must be removed to prevent

the impeller from turning.

On independent ring drive only :

Cut power to impeller and auger motor by switching to off the 60 amp. Breaker

located in the breaker box mounted on the auger frame.

CAUTION :

Failure to do this will result in severe equipment damage.

POWER CORD:

REMEMBER : ON INDEPENDANT RING DRIVE SYSTEM THE 60 AMP, BREAKER MUST

BE IN THE « OFF » POSITION TO PREVENT THE IMPELLER FROM

TURNING.

ON THE LINE SHAFT DRIVE SYSTEM, THE IMPELLER V-BELT MUST

BE REMOVED TO PREVENT THE IMPELLER FROM TURNING.

On powered distributor, guide the motor cord through the upper pedestal hole and down through the pedestal

and impeller.

Pull cord through lower opening in impeller and connect to female connector from the circuit breaker box.


Release spring pressure on the pressure wheel.

Loosen the lock screw for the guide wheel and slide the wheel all the way in. Leave the set screw loose so the

wheel can pivot for raising.

Lubricate all grease points and check oil level in the gearboxes.

Adjust the wall wheels so they are all the way out (toward silo wall).

Check for condition and proper tension of belt on powered distributor. Operate the unloader around the silo at

least once to make sure it moves freely. Observe from the safety of the silo chute. Stop the unloader with

the auger near the main leg of the suspension system or leg nearest chute. You must be able to reach the auger

shroud from the silo door.

Flip the vertical raising wheel against the silo wall. Make sure it turns freely.

Check the condition of the support cables and the cable clamps. Replace the cables if they are frayed.

Place the main power cord connector on the auger shroud so it can be reached from the silo doors.

Raise the unloader to the top of the silo. Always leave about 6’ of suspension cable between the

suspension arms and the cable pulley on the hexapod. This reduces lateral forces on the hexapod. The

unloader can be raised higher for additional silo capacity at the very end of silo filling after the silo

has been filled to this level.

ATTENTION : Always have someone available to observe the unloader from the safety cage platform

or from the top of the silo chute to announce when the unloader is nearing the top.

Never enter a silo under a suspended silo unloader.

Take the power cord up the silo chute and hang the cord support on a ladder rung near the top of the silo.

(Unless unloader is equipped with a cord looping kit.)

Flip the vertical raising wheel to the stored position (away from the silo wall).

Plug in the unloader-distributor (make sure there is sufficient slack in the power cord to prevent pulling the

connection apart) and let it rotate around the silo until the guide wheel is near the silo door.

Turn the guide wheel caster to a level position and tighten its set screw.

Continue operating the unloader around the silo at least one to make sure it moves freely.

Do not connect torque chain to door frame during filling. If optional torque arm is used, store it in storage

bracket. Do not put in door frame during filling.


OPERATING THE DISTRIBUTOR

Always make sure that the unloader-distributor is operating when filling. If the time between loads is less than

three minutes, it may be advisable to allow it to operate continuously to reduce the likelihood of filling with the

distributor not moving.

A normal fill pattern is one which is high and level around the silo wall and sloppes into a low point at the center,

making a large inverted cone. The standard distributor will achieve the pattern in 12’ through 18’ silos. A

powered distributor should be added for larger size silos.

Should the fill pattern become uneven, the distributor should be deliberately parked and fill pattern evened out by

running one or two loads toward the low side.

When the silo is nearly full (check this often), someone must watch from the outside to insure that material is not

dumped on the unloader. The unloader may be raised as high as possible and still keep the wall wheels below the

hexapod plates for topping off the silo (see note below). When using powered distributor the inverted cone may

be filled by disconnecting the powered distributor and operating the unloader, thus allowing the material to fall

near the center of the silo and fill in the inverted cone.

IMPORTANT :

Note : Always have someone available to observe the unloader from the safety cage platform or from the

top of the silo chute to announce when the unloader is nearing the top.

After the silo has been topped off and leveled, the unloader-distributor should be cleaned off and raised out of

contact with the acidic rust producing silage during the fermentation process. It is also a good idea to convert the

machine to unloading at this time since the silo filling blower is usually still set up and can be run to provide

fresh air to the persons in the silo. This is accomplished by reversing the conversion steps listed in the converting

to distributing section.
